RALPH NORTON ADAMS, OF CORVALLIS, OREGON.

WOODWORKING-TOOL Specification of Letters Patent.

Application filed October 14, 1909.

Patented Nov. 15, 1910.

Serial No. 522,667.

To all whom it may concern:

Be it known that I, RALPH N. ADAMs, a citizen of the United States,residing at Gorvallis, in the county of Benton and State of Oregon, haveinvented certain new and useful Improvements in Woodworking-Tools, ofwhich the following is a specification.

My invention relates to improvements in woodworking tools, and theleading object of my invention is to provide a device to facilitate thecutting of wood at an angle.

A further object of the invention is the provision of a device by whichcompound angles may readily and quickly be laid out on squared beams.

With these and other objects of a similar nature as hereinafterdisclosed in view, my invention consists in a woodworking tool embodyingnovel features of construction and combination and arrangement of partsfor service substantially as described and as illustrated in theaccompanying drawings.

Figure 1 represents a perspective view of my device in position on abeam, the tool guiding members both being set at an acute angle to theedge of the beam. Fig. 2 represents a similar view, one of the guidesbeing set at an acute and the other at a right angle to the edge of thebeam. Fig. 3 represents a section through the adjustable slides andguiding members, and, Fig. 4 represents a sectional view taken centrallyof the stock and slides.

In the drawings: The letter a designates a beam, having applied theretomy improved angle marking device. Said device consists of the bodyportion or stock having the two sides B and C, said sides correspondingin every essential feature and in the drawing being shown as meeting atright angles. It will be understood, however, that if desired they maybe constructed to meet at any angle or may be rounded according to theshape of timber upon which the device is to be used. Formed in the innerface of the outer portion of each side is a groove or recess D, whilemounted in said recess is an adjustable slide member E, said member Ehaving a central slot F formed therein the face of the slide adjacent tothe slot being countersunk to receive the head of the screw or bolt Gand permit the head to make a flush joint with the face of the slide.The screw G passes through the stock and is secured on its outer end bythe thumb nut H, the screw thus adjustably securing the slide in therecess D and while normally permitting it to move therein serving tolock the slide in any desired position. Secured 1n the outer end of eachof the slides is a second adjustable screw member J similar to themember G, the head being placed on the inner side of the slide, andmounted on the member J and sliding thereon is the indicating or guidingmember K, said member having a slot L formed therein in which the screwJ moves, the inner face of the guiding member K being of similarconformation to that of the slide in order that the head of the screwmay make a flush joint therewith. It will be observed that I have madethe ends of the guides K of angular or pointed shape, the object beingto permit them to meet more readily at their outer edges, thus enablingthe angle formed by said edges to be exactly drawn to the edge of thetimber.

From the foregoing description taken in connect-ion with the drawingsthe construction and operation of my device will be readily understoodand its advantages fully appreciated by all having any knowledge ofcarpentry or woodworking of any character, and it will be seen that onaccount of the adjustable slides and guides the latter may be set atpractically any angle with reference to the timber and each other and bymeans of the screws G and J be locked in such position and moved alongthe timber or from one piece to another, while to change the angle it ismerely necessary to loosen the thumb nuts.

It will be understood that my device may be made of metal or anysuitable substance and if desired the guides may be provided with meansfor indicating the angle at which they are set, thus obviating thenecessity for using a square or other instrument in setting the device.

I claim:

1. A woodworkers tool, comprising a stock having two sides meeting eachother at an angle, a longitudinally adjustable member carried by eachside of the stock and projecting from one end thereof, means pivotallyand adjustably secured to said members, and means for locking thevarious parts in adjusted position.

2. A tool, having a stock composed of two sides meeting at an angle,slides adjustably secured to said sides and projecting from one endthereof, and guide members havwith a stock comprising two sides meetingat an angle and having a longitudinally disposed groove formed in thework contacting face of each of the sides, of slides mounted in thegrooves, and adjustable guide members carried by the ends of the slides.

4. In a woodworkers tool, the combination with a stock comprising twosides meeting at an angle and each having a longitudinally disposedgroove formed in its work contacting face, of slides mounted in thegrooves, and adjustable guide members carried by the ends of the slides,the depth of said grooves being equal to the thickness of the slide andguide member to permit both the stock and guide member to lie flat uponthe work.

5. In a device of the character described, the combination with a stockhaving a plurality of work contacting converging faces each having agroove formed therein and extending longitudinally thereof, of a slidemounted in each groove, means for adjustably securing said slide inposition, the slides being each provided with a slot in which thesecuring means moves, and a guide member pivotally secured to the outerend of each slide and slidably adjustable with respect thereto.

6. In a device of the character described,

the combination with a stock of substantially L-shape in cross-sectionhaving a longitudinally extending groove formed at the inner side ofeach leg of the L, of a pair of members mounted in each of said grooves,said members being of size to make when superposed a flush joint withthe face of the stock, and one of each pair of said members beingadjust-ably secured to thestock and the other member being secured-tothe first and being universally adjustable with respect thereto. 7

In testimony whereof I affix my signature, in presence of two witnesses.

RALPH NORTON ADAMS.
